It can go either way. On one hand, the continual presence of a substance can result in developing a tolerance, with. weaker immune response.
On the other, repeated exposure can cause the immune response to get stronger with each administration.
Since we don't know if your body is responding to the ingredients in the brew, or something's in there that shouldn't be, I'd err on the side of caution and just get some sterile vials, .22um syringe filters, and filter it into a fresh vial.
All UGL compounds should be filtered as standard practice, in my opinion. Hell, there are medical practitioners and scientists who advocate filtering all compounds prior to injection, pharma produced injectables no exception.
(except vaccines).
